La variabilidad estacional fue más conspicua que la espacial, mientras que la variabilidad nictémera fue la menos marcada. Dentro de cada nivel trófico se observaron diferentes gremios. Nivel I: filtradores (Clupeidae), herbívoros macrófitos (adultos de Sparidae) y detritívoros (D. auratus, D. rhombeus y adultos de E. melanopterus).

La vegetación es un indicador local sintético de la heterogeneidad del paisaje y, especialmente, del grado de conexión entre distintos sectores del paisaje y el régimen de pulsos. Este estudio demuestra que la vegetación fluvial está condicionada por un espectro de condiciones ambientales distinto del que regula a los paisajes terrestres adyacentes. Es posible prever el tipo de paisaje y las especies que tienen mayor probabilidad de instalarse en cada segmento del paisaje de la planicie y, a su vez, para períodos muy largos de aguas altas o de sequías extremas. ····· 1036189567
für 53.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Las masas forestales juegan un papel muy importante como sumideros de carbono (transferencia neta de CO2 del aire a la vegetación y al suelo) ya que, los árboles a través de la fotosíntesis, absorben CO2 del aire para fijarlo y almacenarlo en su biomasa (tronco, ramas, corteza, hojas y raíces) y en el suelo, a través de los aportes de materia orgánica. Si se favorece el crecimiento y desarrollo de los bosques se podrá incrementar esta función de fijación de carbono, contribuyendo a disminuir la cantidad de carbono existente en la atmósfera y minimizando el efecto invernadero. Este estudio pretende cuantificar y modelizar el carbono contenido en los suelos del sabinar, para descubrir la capacidad que tiene como sumidero de carbono. Estos conocimientos son relevantes para un aprovechamiento ordenado y sostenible de los sabinares, desarrollando un plan que proporcione un cierto equilibrio entre el aprovechamiento maderero, pascícola, micológico y paisajístico, procurando conservar su diversidad ecológica y cultural.

El estudio se centra en comparar dos tramos del arroyo de distintas características hidrológicas: la fuente, de caudal permanente y condiciones ambientales constantes, y el tramo final, de carácter temporal y fluctuante. Se abordan diversos aspectos ecológicos como la selección del hábitat por los invertebrados y las relaciones tróficas establecidoas entre ellos y sus recursos, todo ello a través del análisis de la abundancia y biomasa de las especies. Asimismo, se realiza una aproximación a los ciclos de vida de las especies y una revisión de estudios similares llevados a cabo en ríos temporales.

Por otra parte, los suelos en los cuales se apoyan son moderadamente ácidos y poseen contenidos bajos de nutrientes, limitando seriamente su productividad en los períodos de baja actividad biológica. Esas tres características determinan escasa producción invernal y baja calidad del forraje ofrecido en primavera-verano. Al mismo tiempo, el pastoreo con una carga constante de ovinos, vacunos y equinos, ha provocado la degradación, y la consecuente disminución de la productividad de las pasturas naturales. La utilización de fertilizaciones nitrogenadas estratègicas y el manejo del pastoreo constituyen dos herramientas esenciales para aumentar su productividad otoño-invernal y mejorar su composición botánica. ····· 1036189447

La apuesta fundamental del gobierno mexicano se concentró en los Estados Unidos de Norteamérica. En un inicio, México, Estados Unidos y Canadá no contemplaron dentro del TLCAN las repercusiones ambientales de la apertura comercial. Fueron diversos grupos ambientalistas los que empezaron a ejercer presión sobre asuntos colaterales implicados en el Tratado, a saber, el deterioro ambiental y las cuestiones laborales. La unión de varios grupos ambientalistas tri-nacionales dio lugar a los acuerdos paralelos sobre medio ambiente. Su intención era proteger las fronteras comunes frente al deterioro ambiental que la apertura económica podría causar.

The present knowledge of climate variability, climate change is based upon the observed meteorological data. The information beyond the instrumental period is also very important to understand the long term climate change variability on decadal to century scale. However, such past climate data information is limited and discontinuous. Very little information is available on Indian climate, particularly over the Himalayan region earlier to about a century when the instrumental records commenced. The tree-ring records, though shorter in palaeoclimatic time frame, are accurate and their time resolution is to a specific season or year. Preliminary studies based on tree-ring samples in the region beyond 500 years in age with well marked and environmentally sensitive annual growth rings and can be used to reconstruct past climatic variation over the region. ····· 1036189318

The study was conducted in and around RNP to establish the impact of snaring on wildlife conservation. The local community had negative attitude towards wildlife and the park. Bush meat was for domestic and commercial purposes. Poverty was quoted as the major reason for snaring. Sources of snares varied from vandalism, purchase to locally-made and mainly targeted buffalos, Rothschild giraffe, and the Roan antelopes. Majority of the respondents claimed not to have been aware about wildlife laws relating to illegal poaching and bush meat consumption. Majority of the locals were not aware of any community-based project meant to improve their living standards and there was no tourism activity reported in the area.

Most of these works were concentrated on the physico-chemical factors of the water and their correlations with plankton composition. Fresh water plankters are important component in aquatic ecosystems and participate as a link between the trophic levels. These are more valuable as indicators of trophic conditions and respond more rapidly to the environmental changes than the fishes. Therefore, they are of considerable potential value as water quality indicators. This book is useful for the young researchers as it guides to assess trophic status using zooplankton as indicator.

Farmers perceptions on the genesis of the termite problem were supported by results from trials on consumption of vegetation by termites which revealed that foraging intensity of termites was higher in areas cleared of vegetation. The termite assemblages were dominated by generalist feeders that predominantly feed on liter. The study concluded that the termites in the study area are largely litter feeders but resort to consumption of vegetation when inappropriate rangeland management techniques deprive them of adequate feed (litter) sources implying that techniques that enhance accumulation of adequate litter and maintenance of adequate basal cover are critical in mitigating termite damage on rangeland vegetation. ····· 1036188959

However, mutations in both are inevitable and the same has shaped the world as we know it today. Hence a discourse on religion, environment and interplay of both on each other and on the lives of human being is inevitable and the same is attempted in this work.

It has been categorized as one of the 17 most polluting industries in India due to discharge of huge volumes of highly coloured and toxic wastewater (effluent) in the environment. It causes pollution of land (soil), air and water. Heavy metals like mercury, cadmium and lead are present in pulp and paper mill effluent. These toxic elements may cause physical problem to human beings and animals by entering the food chains. The wastewater generated in a pulp and paper mill should be treated effectively so that it could be utilized for irrigation purpose without any harmful effects on environment, human and livestock health. This volume attempts to portray the studies carried out on the physicochemical characteristics of a stream carrying effluent load from a pulp and paper mill and on accumulation of heavy metals in the grains and straw of wheat crop irrigated with the wastewater.
